A researcher designed an experiment to demonstrate the process of soil erosion. He placed a bar of soap in a flat dish and left it under a slow running tap so that water falls directly on the soap bar. After two hours, the researcher noticed that the part of the soap on which water was falling had been washed away and a hole had formed in the bar. The researcher concludes that the rate of soil erosion can be calculated by using the soap bar model and can be applied to real-life scenarios. Is the researcher’s technique reliable for testing real-life erosion rates? (TWO ANSWERS)
No, because the flow of tap water is not comparable to the flow of water in natural conditions.
Yes, because it shows the erosion of the top layer of a surface by water.
Yes, because it demonstrates the speed with which erosion of soil can take place.
No, because the texture of soap is not comparable to the texture of soil.
Which of the following must be done for the results of an experiment to be considered valid?
The experiment must be repeated numerous times and the same results are obtained.
The results must be only quantitative.
The results must be shown in a graph.
The results must be published in a national journal.
Wyatt conducted an experiment to test the effectiveness of three different household cleansers to destroy colonies of bacteria. Wyatt predicted that Cleanser 3 would be the most effective.

The samples were then transferred to a culture medium where Wyatt would count the number of colonies that grew on each culture. Wyatt is missing a control for his experiment. Which of the following would be the best control for his experiment?
Use Cleanser 1 and 2 on the kitchen counter and Cleanser 3 on the bathroom sink.
Test the number of bacteria on the kitchen counter and bathroom sink before and after scrubbing with water.
Use only Cleanser 1 on both the kitchen counter and bathroom sink.
Test the number of bacteria on the counters and sinks without scrubbing with water or cleansers.
Which procedure should NOT be used to safely dissect an organism?
